What 98 owners told NHTSA about the 2017 GMC Sierra 2500 Hd

The pigtails to the injectors are prone to failure. The vehicle without warning throws multiple codes and immediately limits power and speed while shaking. This can cause a dangerous driving situation. This is a known problem and is on many online forums as a common failure. The repair shop gets so many of these that they were able to diagnose the issue over the phone and noted that it usually happens around the 200k mile mark. However many reported this as an issue while under warranty. The issue is with the metal connector material being prone to failure and arcing.

The def heater gm part#84162464 has broken on my truck. There are many owners with the same problem on their duramax diesels. This has been an issue since def tanks were mandated by the federal government. The replacement cost is estimated to be $2000. from my local dealership. The truck had 50,000 miles on it when the heater first started working intermittently. I'm reporting this so it can be logged in as another incident for failing, poorly engineered parts.
